Nuaire Drimaster PIV Unit

Limited supply only - Being Nuaire's top Tier 1 Distributor, we have bought all of Nuaire's stock - so grab a bargain whilst we still have some - they won't last long!

Cure condensation dampness and remove allergens and pollutants from the home with the low- energy ventilation system, from the inventors of PIV. The Drimaster offers cost-effective, whole home ventilation for two and three story homes with lofts.

The Drimaster offers cost-effective ventilation for the whole property using the tried and tested Positive Input Ventilation (PIV) principle, where fresh, filtered air is introduced into the home at a continuous rate, encouraging movement of air from inside to outside. This process removes condensation, allergens such as dust mites, and the pollutants caused by cooking and cleaning from the air. The results are a fresh and healthy indoor environment in which condensation and mould cannot exist, and where indoor pollutants including harmful Radon gas are kept to a minimum - all great news for allergy sufferers.

The Drimaster is a low-energy whole home ventilation is easy to install and cheap to run. Fitted in the loft, out of site and with no holes to knock through walls, the non-disruptive installation makes it an ideal solution for retro-fit projects.

Cut a circular hole 225mm diameter in the ceiling between two convenient joists.

Position the diffuser frame and secure it to the underside of the ceiling with the 1 1 /2“ x 8 csk. hd. screws and plugs provided.

Attach the diffuser plate to the frame using the four built in press on clips provided.

Foam strips should also be used as required when this method of installing the diffuser is used.

Frequently asked Questions:

Q. What is a Nuaire Drimaster?

A. It is a small, loft mounted, air cleaning/moving device that continuously inputs filtered fresh air into the dwelling from outside. The only ‘visible’ component when installed is the central input diffuser which is usually located in the central hallway/stairwell ceiling.

Q. What does the unit do?

A. The unit will cure and/or prevent the problems associated with condensation in your home, providing a cleaner, healthier living environment for all occupants. The unit will prevent mould growth on walls, ceilings, furniture, clothes and curtains. The unit also radicates the musty smells evident in homes with severe condensation problems.

Q. How does it work?

A. Simply and very efficiently. Outside air is drawn into the loft where it is slightly warmed by the free heat in the loft caused by solar radiation and the heat lost from the property into the loft. This air is drawn into the unit, filtered and then ducted into a central area (typically the hallway / stairwell) of the dwelling. As the air is supplied into the dwelling it mixes with the warmer air that naturally accumulates at ceiling level taking advantage of the heat from this warm air you have paid for but are not making use of. This tempered, fresh, clean air then continuously and gently dilutes, displaces and replaces the air within your home. The result is a home free from serious condensation and a more pleasant and comfortable environment.

Q. How do I operate the unit?

A. You don’t. The unit is completely automatic, switching from ‘normal’ to ‘boost’ and ‘off’ as required to make optimum use of energy

Q. What maintenance is required for the unit?

A. Very little. The only maintenance required is the replacement of the filters every 5 years. (The filter can also be vacuum cleaned periodically if necessary).

Q. How will I remember to clean the filters?

A. When the filters become dirty, the unit does not input as much air into the dwelling, Condensation and musty smells may become evident. This will be a signal for you to check and clean or replace the filters as necessary. - Click here to purchase replacement filters

Nuaire NUADM Product Reviews

Did everything it said it would! No more condensation or mould. A little bit cool on the landing and with hindsight I would have bought the model with a control on the ceiling so I don't have to go into the loft to adjust the setting. I've now got it set to the correct setting and it has made a huge positive difference. Definitely recommend this product.

I can totally agree with all the 5 star ratings given for this product.
The installation is simple....the issue raised about fitting the flexible pipe onto the diffuser is solved by running the flexible through the ceiling and using 2 people to stretch the flexible over the diffuser outlet from the landing side where you can get your hands inside and outside the diffuser.Then screw on the diffuser to the landing ceiling.
After one day on setting 3 the house windows were completely dry.In addition the house smelt fresh.
We did think there was a small draft from the diffuser so we dropped it down to setting 1.At this setting we had a small amount of condensation ,so we have reset to 2.
There is no discernible noise at level 3.
Our house is a 4 bedroom 1930 detached house.
We did not buy the heater option and we do not think it is needed in our situation.
In addition to the excellent product the delivery,packaging from I-sells was first class.

Good construction quality, clear instructions, straight forward installation and very quiet running. The only improvement would be if the programming buttons could be mounted on the top of the unit. That said, once set up you are unlikely to need to change the settings. This minor criticism would not be an issue on the newer versions with remote speed, temperature and humidity controls.

The Nuaire Drimaster has only been installed a month, but already we are seeing little to no condensation on the windows. Black mould spots in the corner of walls has disappeared and old mould spots just wipe away. Installation instructions were very good and the install was very straight forward. So far so good. Very happy with our purchase.

Purchased the item in August and have held off reviewing until the cold hit. Unit was easy to install as per other reviews the only difficulty being the fitting of he flexi onto the defuser spigot. Unit is fitted in the loft with the defuser exiting into the stair well. There is a cooling effect which is noticeable in the summer providing a relief from the heat. Now it has become cold the cooling effect not a problem and we have got use to it. The house feels and smells fresher, I have a humidity sensor which use to record humidity at 75% to 90% in our bedroom it now does not get over 35%. Before fitting once the temperature reduced over night all our windows would be covered in condensation with puddles on the cills. Now we only see approximately 1 inch of misting on the bottom of each glass pane with no puddles. Unit is installed in a 3 bedroom house and set to speed number two. For such a simple concept it does a great job, wish I had fitted one years ago.

Installed this positive airflow fan 10 days ago.
Was easy to install, would recommend the right size hole saw to cut into the ceiling.
As for results: we have an upside down house on a hill with two rooms built into voids so no windows. After work was done such as stud wall and tanking to deal with the water dripping down the walls there was still a severe damp element in the air. We had mould spores on doors windows and walls with full coverage of condensation on all windows.
First morning after install on power level 2 all windows were dry completely and the air felt fresher and less humid. So although it was 2 or 3 degrees cooler in the lounge upstairs it felt warmer because of the drier air.
We have a ten year who suffers from croup and asthama who confirms he feels an improvement on his chest.
Previously i have woken in the night to the feeling of extremely damp duvet covers and damp clothing in drawers and cupboards...this unit has instantly cured this issue.

Only been fitted for a few days but have already noticed the difference. On the first night only had a slight mist on the windows but have had nothing at all since. Have noticed that it is slightly cooler upstairs though as we didn't have the unit with the heater. Can put up with that though if it solves the problem of mould and damp! Very pleased so far.

I could not believe the effect the this product had on our home! I finished the installation around 2pm and the following morning we had no condensation on any window in our three bedroom bungalow. We had been wiping down the windows ever since we moved in 3 years ago. Anyone who has condensation problems should seriously consider buying a Nuaire. The unit was installed in the corner of our hallway near the front door - our front door is on the side of our long narrow bungalow and I was concerned that this may be a problem, but I needn't of worried as all windows were dry after the first night. One tip that helped me was to feed the grey trunking through the ceiling and then fit to the defuser using duct tape then screw the defuse to the ceiling - because trying to fit the trunking which is a very tight fit on the defuser whilst balancing on ceiling joists is not fun. Fantastic product AND our house feels warmer.

Not a sign of condensation now. A+++++. I do not have the heating element model as it blows warm air from the loft into the living space.
If you are considering buying one, don't waste any more time - just buy it.

Fantastic piece of kit! We've had damp problems for many years - condensation build up on our double-glazed windows, meaning we had to clear the water off the windows every morning & a build up of mould in cold spots of the house, as well as mould on clothes in the wardrobes, etc. We've been looking for a solution to the damp problem for years, so decided to try this, even though we were a bit sceptical if this would work. The day after fitting this, there wasn't a drop of condensation on the windows, despite it being a cold night. The humidity has dropped from 70% to around 50% & the air is noticeably fresher throughout the house. We only need this on setting 2 of 6, which is only slightly audible if you go up in the loft & only uses a tiny amount of power. My only regret is that I really wish I'd known about this years ago! If you have damp problems, invest in one as soon as you can!

Purchased the drimaster in an attempt to sort out our condensation problems and the related black mold. Excellent fast delivery from i-sells, installation fairly easy if you have some basic diy skills. Initially set the speed to 2. Within 48 hours we noticed a huge improvement, 1 week on and our condensation problem has all but gone. We barely notice the unit is running, there is no noise which can be heard, we haven't noticed any problems with a draft either. The stairwell is slightly cooler when the central heating is switched off, but nothing unbearable. If you'very got damp/condensation problems this could be your answer. Not cheap but a sound investment. Highly recommended.

Installed in the loft over the stairwell. The noise level from the fan is fairly low. Time will tell how effective it is, though a small bedroom next to the bathroom has suffered from black mould on the ceiling this has now been eradicated? Turning on the unit to full blast with a switch sited outside the kitchen door helps keep cooking odours from invading the rest of the house!

I have put 15 of these in various properties ranging from penthouse flats to 4 bed houses and have had great results from all of them. They achieve what they claim - a marked reduction in condensation levels in the properties. My tenants have been very impressed with the results, as have I (I have 1 in my own house as well), and it helps me retain tenants whilst meeting the requirements of the latest building control standards.
The only negative feedback is over the operating noise level. These Nuaire units are not as quiet as others out there on the market BUT they are half the price. Overall I am very happy to recommend them to any householder or landlord.

Louise BallDate Added: Friday 24 January, 2014

A fantastic product. Noticed a huge difference in condensation levels on the windows overnight as soon as it was installed. The house suffered very badly from green mould on the walls and the freshly decorated paint had peeled away from under the windows. A dehumidifier was on constantly and filling up regularly with water in all the upstairs rooms. The house now feels fresher, no smell of damp, it really has made a huge difference.
There is a very slight humming noise from the vent in the loft ceiling and there it feels colder upstairs but any downsides are far outweighed by the results in curing the damp/condensation.
The only slight criticism I have is that the initial settings aren't very clear in the manual, I'm still not sure it is set up properly but am reluctant to change it when it is working so well.

Can I still have a fan to expel the steam in the bath room and above the kitchen hob.

Question by Richard Brown, 01-08-2015

Hello Richard,

You can indeed combine a Postive Input System with an Extractor Fan. In fact it is nessessary to have a source of passive or extract ventilation to work in conjunction with a Positive Input System to allow the humid air to escape the property.

NUAIRE DRIMASTER POSITIVE PRESSURE UNIT

My windows run with condensation, will this unit help to elevate the problem.

Question by Richard Brown, 04-08-2015

Hello Richard,

Positive Pressure Units are one method to help combat a condensation and mould issue. They work by pumping air from the loft in to the property and forcing the air out through natural or purpose-fitted leakage points in the property, such as door gaps, window seals, and air-bricks.

Whether this will be effective in you case will depend upon various factors such as the construction of your property, existing extractor fans, and lifestyle habits. I suggest you give our friendly sales team a call on 0208 463 9696 and they will be happy to advise as to the suitability.

PIV vs Dehumidifier

My property has single glazed sash windows which suffer from condensation & mould. Please can you tell me the advantages of a PIV unit over a dehumidifier to help me decide on which product to go for?

Question by Sachen, 08-09-2015

Hello Sachen

Thank you for your question

The dehumidifier only extracts moisture where as the PIV unit will pump air into the property and force air out of the property via leakage points which are Trickle Vents, Letter box, Wall Vents. The unit you are looking at also comes with a heater the code for this model is QS10002

running cost

I have a tenanted 2 bed bungalow with condensation/mould problem, what would the basic running cost be and does it have to be on all year round. As all doors are leading off of a hallway would it be best to install it in the hallway and do the doors have to be left open. Thank you

Question by Anita Holtom, 10-10-2015

Hello Anita,

Further to our conversation earlier this morning, I would recommend either the Nuaire Drimaster (NUADM) or Nuaire Drimaster Heat (NUADMHEAT), depending on the temperature of your loft during winter.

The unit would be best positioned in the loft as long as doors are kept open or that there is sufficient space underneath the door to allow the air to circulate.

As we discussed you will also need passive ventilation (airbricks) or extract ventilation (Bathroom or Kitchen extractor fans) to ensure that the stale condensation-laden air can be forced out of the property.

Please do not hesitate to contact me if you have any questions or would like to place the order.

Kind regards,

Michael

Correct Unit

Hi there
We had cavity wall installation installed a couple of years back and have had nothing but trouble due to excess condensation. The electrician I use has recommended one of these and has stated that they do the job very well. What I need to know is the following. I have a 3 bed semi with a converted loft so there is only a small space for the unit behind the small walls in the loft. There is plenty of airflow into the loft and I can install a couple of extra vents into the walls to allow the moist air to pass through so that won't cause an issue but would need some advice on what model number I would need if there are different sizes. Thanks Shaun F

Question by Shaun Forstr, 11-11-2015

Hello Shaun

Thank you for your question. The unit is fitted to a joist in the loft and the diffuser is fitted in the ceiling in the hall. The measurements of the unit are from filter to filter 900mm, from the top of the unit to the bottom of the unit is 300mm and the bottom of the unit is 336mm. There is a PDF on the unit on our web site that you can have a look at. If you require any further help please do not hesitate to contact me on 0208 463 9683

I have an underground concrete bunker (converted water resevoir) It is dry during the summer but suffers from condensation on the ceiling during the winter. It is approx 20ft x 30 ft x 10ft. Would this product solve my condensation problem.

Question by Dave, 01-12-2015

Hello Dave,

Do you have any other forms of ventilation in this bunker? When we have previously provided ventilation systems for bunkers (Military and non-military)or other underground applications we have utilised heat recovery systems whichboth supply and extract air. A Drimaster, without other forms of ventilation,would probably not be effective.

If you can provide me with some further information regarding your layout and the applicationI can provide some alternative solutions.

Kind regards,

Michael

Power Cut

In the event of a power cut, would the unit go to the pre selected fan speed or full fan speed when power is restored.
Is it possible to control the fan speed with an external switch?

Question by James Latimer, 01-12-2015

Hello James

Thank you for your question. There is a battery within the unit and will last for approx. 3yrs and will store your settings. If after that time there is a fault on the battery it will restore to factory settings. Also this unit can not be controlled via a switch.

Please could you let me know the size of the vent plate, also I wanted to install on the top floor of our 3 story house, there is a small landing at the top of the stair well that has a smoke alarm. The top floor is just a bedroom with this small landing, could I put the vent out into the bedroom or would it work better if I move the smoke alarm and install on the landing. (i see from a previous question you answered about proximity of smoke alarm). On this note is there any proximity issues with ceiling lights?

Question by Gary Furneaux, 28-01-2016

Hello Gary

Thank you for your questions. The unit for your application will be the Nuaire Drimaster 3s product code QS18854. You will have to move the fire alarm and install on the landing making sure that the fire alarm is 1.5meters away from the diffuser. There is no proximity issues with the lights. And the measurements for the diffuser is 303x303 square.

Question by Janet, 01-02-2016

The ideal installation would be in the ceiling,however you can site the diffuser on the wall if no other option is available.The Drimaster unit comes complete with foam inserts used to blank off supplyair sections of the diffuser where non standard installs are required. Blank off one section of the diffuser where the airway is facing towards the ceiling(thus stopping the air coming out and being directed straight upwards to the ceiling), leaving the other three sections of the diffuser open to supply air into the property

Best Solution

I am buying a small 2 bed bungalow in an area that has a 3 to 5% chance of having a high level of radon gas build up inside a property. I have heard that a positive ventilation system can be a solution. Can you recommend which of your products would be suitable.

Question by Donald Neave, 01-02-2016

Hello Donald

Thank you for your question. The Drimaster or the Drimaster heat unit will do your application if the loft has ventilation. The Drimaster unit will filter the cool air from the loft into the property where as the Drimaster Heat unit will filter in warm air. The Drimaster offers cost-effective ventilation for the whole property using the tried and tested Positive Input Ventilation (PIV) principle, where fresh, filtered air is introduced into the home at a continuous rate, encouraging movement of air from inside to outside. This process removes condensation, allergens such as dust mites, and the pollutants caused by cooking and cleaning from the air. The results are a fresh and healthy indoor environment in which condensation and mould cannot exist, and where indoor pollutants including harmful Radon gas are kept to a minimum.

Question by P Harvey, 14-02-2016

Hello Paul,

You ideally want to supply air into a central area of the property so that the air can gently diffuse throughout the property. Ideally this will be a location where several rooms lead-off.

If you are unable to install in the interconnecting hallway described, perhaps there is another area where you could fit the unit that leads off on to other rooms. If you could send me a quick sketch perhaps we can advise further?

effect on loft

If I fitted one of these in my loft as directed (with the vent above the stairs )would it stop damp /mould growth in the loft itself?

Question by russell webb, 20-02-2016

Hello Russell

Thank you for your question. The answer is no it will only do the property. If you have damp/mould growth in your loft space I would check that you have ventilation in the loft as this unit will require the fresh air from the outside to be filtered into the property and if there is no ventilation in the loft this is why you are experiencing damp in the loft space.

ONE BEDROOM FLAT

Hi, I've got a one bedroom single storey flat that has loft space. Due to building regulations, I've had to put a fire door on the bedroom, kitchen/lounge and the boiler/washing machine room. I have an extractor fan in the bathroom and in the kitchen/lounge. I have serious condensation problems especially in the bedroom as there is no ventilation at all. I've had the builder install vents in the ceiling of the bedroom and kitchen/lounge (not mechanical) but this has not helped. I'm going to get him to put trickle vents in the windows next but was considering installing the muaire drimaster PPU as well. If the air pumped into the room only goes back into the loft will it work? I cannot guarantee that the tenants will leave the trickle vents open (the last tenants would not open the windows and claimed it was damp). Many thanks for your help.

Question by Mari Roberts, 20-03-2016

Hello Mari

Thank you for your question. The Drimaster unit has to be fitted into a ventilated loft. With regard to the fire doors you would have to contact the manufacturer to see if anything can be shaved of the doors to allow the air to filter underneath.

remote control

Do any of the drymaster series have remote control for speed and heat on/off

Question by Alan Taylor, 01-07-2016

Hi Alan

From what I can see there is no true remote control available, there is however, a remote temperature sensor with a clip in holder, because the temperature setting (to programme boost mode) means it which appears to be adjustable though with limits! Please see link below which has installation instructions to see if this meets your needs.

The loft should be well ventilated (eaves, ridge tiles, tile vents or soffit vents) and the optimum location for the input air would be a central area such as the entrance hall or a hall from which doors to several rooms are located.

I hope this answers your question.

general query

what is the difference between this model and the 2000?
thanks

Question by trevor, 10-07-2016

Hi Trevor

The Dri Master is a PIV intended for locating in a loft and providing fresh filtered air to combat condensation in a house.

Where there is no loft void (ie a flat) this unit would not look too attractive and the airflow input volume would most likely be in excess of that required.

The Flatmaster is more streamlined and designed to draw outside air through the wall its input volume is also 50% of the Drimaster because it is providing air to one level not two.

Note that both machines have heater options.

I hope this answers your question.

Controlling damp air in a Cellar

Do you have any products that are effective at eliminating damp air in cellars?

Question by Mr K Troman-Green, 25-08-2016

Hello Mr Troman-Green

The short answer is yes, however, the system we would recommend would depend upon what the cellar is used for and we would need to know:-

Is it just storage?

Has it been converted to living accomodation?

Or recreational facilities?

Is there any means of vapour creation in the cellar?

Are all of the walls earth retaining?

What ventilation does the cellar have at present?

Is it heated?

The answer to these questions may help us to recommend an appropriate product or at least narrow the options.

Maximum house area for a unit ?

many thanks

Question by simon richardson, 26-09-2016

Hello Simon

I assume you are enquiring after Positive Input PIV (top of the stairs) system

in which case we would recommend the Drimaster 365 as it can be set on one of six speeds and the manufacturer describes this as 1-2 bedroom flat (lowest speed) up to 5 bedroom / 7 occupants house (highest speed).

Therefore somewhere in between should be a setting suitable for your property.

Please note that it is still important to have adequate ventilation in the bathroom/s and kitchen.

Filters

Hi, how do the filters perform - my loft, although well vented is quite dusty and has quite a bit of insulation fibres floating around in it. Thanks!

Question by Alex Barlow, 11-10-2016

Hello Alex

Because the installation is also likely to kick up some more dust and fibres I would suggest that after the initial installation you get the habit of going into the loft and vacuuming the filters every 4 - 6 weeks (nothing will get through this is to keep the airflow free). You will probably only need to do this two or three times. Then wash them every 12 - 18 months.

I hope this helps.Ian

Do I have to keep all internal doors open

I want to fit a drimaster in the attic of a 3 bed bungalow with the exit vent in an internal central hallway. The tenant tends to keep all the doors off the hallway closed (although they are not particularly close fitting doors) Will this affect the function of the unit to reduce condensation problems

Question by annalisa barrelet, 25-10-2016

Hello Annalise

As you rightly state, doors in domestic dwellings are not airtight so there will be pressure created and leakage into adjacent rooms and every day domestic activity will cause the movement of air through the property so we don't think this will cause a problem.

Which units run continuously throught the year?

All units seem to suggest they have auto shut off in the summer months. I am looking for one that runs 24/7, whatever the time of year & temperature - is this an option?

Question by Andy Patterson, 06-11-2016

Hello Andy,

At the time of installation the installer selects from 6 Air Volume (Speed) settings and 5 different temperature control settings.

Based on your description, it would seem that speed setting 3 is desirable for your case.

"This option removes the temperature sensing function out of the unit. On this option the unit will operate continuously in ‘Normal Operation Mode” depending on the volume control setting selected."

This would seem like the best setting for your application and will remove the heat recovery/summer standy functions of the machine. These functions could always be turned on at a later stage if required.

Just as an advisory - you have posted this question from the older 'Drimaster' product listing, bt this version is soon to be superseded by the more modern Drimaster Eco range, with more control options and a longer warranty for most models. We still stock and supply both models, but Nuaire are due to cease production of this model in late 2016/early 2017.

If you have any questions on the difference between the various Drimaster and Drimaster Eco models and their suitability for your property, please do not hesitate to give me a call on 020 8463 9661 and I would be happy to discuss your requirements further.

Hello Terry

The sensor has three LED indicators

Red - this will flash if the filters require cleaning.

Amber - This indicates the machine is working normally

Green - This indicates the unit is working in Heat Recovery mode and usually activates when the loft temperature exceeds that of the dwelling (at least the air temp in the vicinity of the sensor).

old house

being a very old house our loft has a layer of coal dust, would this affect the quality of air being pushed into the rest of the house,and would the drimaster help with the mould at ceiling height at the top of the stairs caused by condensation.

Question by mike kirvan, 04-01-2017

Hello Mike

To answer the second part of your question first the answer is yes, the system is a condensation and mould control product.

The unit draws air into the loft through its natural ventilation (eaves, tile vents, soffit vents or ridge tile vents) and by doing this it will necessarily create some air turbulence which may disturb any dust in the loft, the air quality being introduced to the dwelling should not be too badly affected as it is fresh air from outside however, it is likely the filters will become coated quite regularly over the initial few months after installation and require constant cleaning. If the coal dust is layered over loft insulation we would probably recommend removing it and installing new insulation.

I hope this helps.

Question by david brogan, 09-01-2017

Hi David

Does this mean there is no ventilation in the bathroom or kitchen?

This system should not have a problem as no house is totally airtight (a keyhole is an air path).

There is no reason to doubt (with adequate bathroom and kitchen ventilation) that the system would not work and also dry out the loft at the same time.

Condensation

I have a 2bed terraced house which has a 2storey extension kitchen &bathroom which has single skin walls .I have bad condensation problems in both .Would you recommend the Nuaire Drimaster for this problem if so should it be fitted on the landing as the kitchen is quite a long way from the landing although next to the bathroom.
Regards CT Miller

Question by Colin miller, 05-02-2017

Hi Colin

The Drimaster is a condensation control unit for dwellings that suffer condensation problems throughout. If it is just the kitchen and bathroom that are affected this will be partly due to the single skin nature of the extension (poor insulation) but I am also interested as to what means of extraction you currently have for these rooms?

The Drimaster is designed to work in properties that have adequate ventilation in the moisture producing rooms.

Ihave a 3bed detached house two story with loft we suffer with musky smell in damp cold weather and underside of bitumen roof felt is wet especially in cold weather the loft is well insulated

Question by Lyn Doran, 29-10-2017

Hello Lyn

The damp musky smell you describe may be emanating from substrate below the house if you have suspended floors or may be coming from the roof void as your description indicates there is a condensation problem through a lack of loft ventilation, this needs to be addressed if considering loft sited PIV.

Have a quick check of your roof from outside and look for tile vents, ridge tile vents, or airbricks in any gable ends, inspect the loft from inside in the dark and look to see if you can see daylight. You say the loft is well insulated and this may have blocked soffit vents or be tucked into the overhanging eaves restricting the natural airflow. Once the loft ventilation is improved or reinstated the Nuaire DriMaster PIV would be a cost effective means of ventilation for the house if the input diffuser can be located at high level in the stairwell (QS45546).
